AI Technical Summary
In the prior art, the interfacial adhesion between polymer materials and substrates is insufficient, and problems such as peeling, delamination, peeling or localized decrease in adhesion are prone to occur during drying, curing, thermal aging or solvent contact. In particular, the interfacial stability is insufficient under thermal aging and solvent contact conditions.
A polymer composition comprising a polymer material, a first organic solvent, and an adhesion promoter containing a benzotriazole formamide silane structure is used to form a polymer/substrate composite interface by forming a film or curing on the substrate surface. The interface bonding is improved by utilizing the multi-point synergistic effect of the benzotriazole ring, formamide bond, secondary amine group, and trialkoxysilane group.
It improves the adhesion between polymer materials and substrates and the stability of the composite interface, reduces the reliance on surface treatment processes, and enhances the stability of the interface under aging treatment and solvent contact conditions.
